Magnesium is a chemical element with atomic number 12 which means there are 12 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.
It is a white, non-sandy fine powder; and has a slight odor with a slippery feel when it comes in contact with the skin. Magnesium stearate is insoluble in water, ethanol or ether. It dissolves in hot water and hot ethanol, and decomposes into stearic acid and corresponding magnesium salt in case of acid. The structural formula is as follows.
